PORTABLE POWER WOOD-SAWING APPARATUS.

7 Application filed March 2, 1922. Serial No. 540,586.

This iny ention relates to a portable power driven wood sawing apparatus.

The object of the inventionis' to provide an apparatus of this typewhich may readily be hauled about from place to place, operated and controlled by one man. 7

The object of the invention is further to provide an apparatus of this type in which an ordinary form of hydrocarbon combustion engine is employed and in which the shaft of the engine is directly connected to the shaft of the saw so that there are no,

losses of power through the slipping of belts or other power transmitting devices or through misalignment.

The object of the invention is further to provide an apparatus of this type in which the engine and saw shaft extend longitudinally and centrally of the supporting frame and all the parts of the apparatus are arranged symmetrically or in substantially balanced relation with respect to the longitudinal central axis so that there is a minimum of vibration, and a balanced structure.

is produced giving the most effective results in operation.

The object of the invention is further to produce an apparatus of this type which is compact in form, light in weight and so conveniently mounted on its wheels that it is possible for one man under favorable conditions to move it about'from place to place.

The object of the invention is further to provide an apparatus of this type which requires a relatively small amount of power for its operation and which will run without the necessity of the supporting frame being in a level position.

The object of the invention is further to provide an apparatus of this type in which one set of wheels is carried by a bolster pivoted to the supporting frame on a central vertical axis to permit the steering of the apparatus and in which means are provided to lock the bolster to the frame toprevent a relatively transverse tilting movement and thus position the supporting frame firmly for the sawing operation.

These and other objects and features of the invention will appear more fully from the accompanying description and drawings and will be particularly pointed out in the claim.

In the drawings Fig. 1 isa top view of an apparatus embodying a preferred form of the invention, the draft tongue being shown partially broken away. 1 i Fig. 2 is a front elevation partially broken away and partially in vertical cross section showing the front end of the frame, the steering bolster, wheels and draft tongue; 7

Fig. 3 is a detail in vertical cross section taken on the line 3-3 of Fig. 1 with the bolster shown in locked position and the draft tongue shown in dotted lines in draft Po t a Fig. 1 is aside elevation of the main and rear portion of the. apparatus shown in Fig. 1;

Fig. 5 is a view in'vertical cross section taken on the line 55 of Fig. 1 showing the wheels 3 are carried on an axle 4 mounted in hangers 5 secured to the bottom of the beams 1 and 2.

The-front wheels 6 are carried on an aXle 7 and in turn carried by'a bolster 8, pivoted on a central vertical axis by the-bolt or king pin 9 to a hanger 10 secured to the beams 1 and 2 at the front end. The front wheels are turned about the bolt 9 to permit the steering of the apparatus and the apparatus is drawn by means of a steeringbifurcated draft tongue 11. In the formshown this tongue is shown as an iron rod bent into loop form with its ends bent about the axle 7 so as to pivot thereon.

It is very desirable that when the apparatus is set up in position for the sawing operation the supporting frames shall be rigidly and firmly positioned. The invention provides a means for locking the front bolster to the frame to prevent any relative transverse tilting movementbetween the frame and the front bolster with its wheels. A simple and effective means for securing this result is illustrated as embodying one form of this feature of theinvention. A plate 12 extends transversely of and is Se? cured to the top of the beams 1 and2 at the ront end of the frame move the axle *1".

At its rear end, the Si 23 carries the circular saw 26 Which pr ably is positioned beyond the rear end of the supp rting frame and may thus have the necessary clearance Without requiring any higher mounting ofthe shaft with respect to the frame than is required by the position of the engine.

A heavy fly Wheel 27 is mounted on the saw shaft to provide for the necessary momentum.

The wood is fed to the saw by a table extending longitudinally of the frame and mounted thereon at one side of the shaft for transverse movement between the saw an the engine. Preferably this table i, mounted to tilt or pivot and thus secure tile necessary transverse movement.
